Comment 0 for bug 1999816

When for some reason the df command fails to get the disk free space (for example timeout on a heavily loaded system) the result is a harcoded value of "unknown". As this is not a valid number this generates arithmetic errors when the "rabbitmqctl status" command is run and tries to divide that value to convert it to another unit.

This has been fixed upstream here: https://github.com/rabbitmq/rabbitmq-server/pull/5726
